Could you see the tip of Russia form the Sutton coldfield TV Mast?
You would not be able to see any part of Russia from a mast in Sutton Coldfield, because of the curve of the earth, You would not be able to see beyond a limited horizon beyond which the earth’s surface ‘falls away’. You might be able to see Russia if you went up into the air high enough, but we are talking about going up high enough to go into orbit.
